The six advantages of
18650 lithium batteries.
18650 lithium batteries (single) are usually used up when the voltage is below 3V (of course, the specific threshold also depends on the protection board, as well as 2.8V, 3.2V, etc.). Most lithium batteries are set to not discharge below a voltage of 3.2V, which can cause damage to the battery. In addition, the 18650 lithium battery has a fully charged voltage of 4.2V, and once it reaches 4.2V, it can no longer be charged. For traditional lead-acid batteries, most charging methods are to charge them before going to bed at night and unplug them after waking up. The above two points are some special aspects of lithium batteries that need to be noted. 18650 lithium batteries have many advantages, let's take a look together.
Widely used: automotive lithium batteries, garden tool lithium batteries, electric tool lithium batteries, construction equipment, low-speed vehicles, etc., with a very wide range of applications.
On demand customization: Multiple 18650 lithium batteries can be connected in series and parallel to form a battery pack, and the number of series and parallel connections can be determined according to the needs.
Low internal resistance: The internal resistance of lithium batteries is smaller than that of liquid batteries, which greatly reduces their own self consumption and makes the battery more efficient.
No memory effect: use and charge as needed, but of course, pay attention to over discharging and over charging. The meaning of no memory effect is that there is no need to use up the battery before charging, which is very convenient.
High voltage: A single
18650 lithium battery has several common voltages such as 3.6/3.8/4.2V, which is much higher than the voltage of lead-acid and nickel hydrogen batteries. Some users may ask, what is the use of high voltage? Isn't it possible to form the desired voltage through series and parallel connections? The statement is quite accurate, but there is a problem here, which is the space for storing batteries. Low voltage means that more batteries are needed, so it is not very convenient to have low voltage requirements for space.
Long service life: The cyclic service life is generally more than twice that of ordinary batteries.
